Wiseco Ford 4.6L FLAT TOP 1.220 X 91MM Piston Shelf Stock Kit

When you're building a serious performance engine for your Ford, starting with a solid set of pistons is key. This kit from Wiseco includes a full set of eight flat-top pistons, designed for Ford's 4.6L and 5.4L Modular engines. These aren't your average pistons; they're built for demanding applications where strength and reliability are paramount, like in performance builds for vehicles such as the Ford Mustang, F-150, or Expedition.

Wiseco forges these pistons in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited to handle the stresses of heavy or severe duty use. They also feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The piston crowns are fully machined, and the ring grooves are precision-machined with anti-detonation features and additional sealing enhancements to ensure a strong seal between the piston and cylinder wall. Plus, they include forced pin oiling to keep the wrist pins properly lubricated under high loads.

This set is designed as a shelf-stock replacement for many Ford Modular engines, fitting a wide range of vehicles including the Crown Victoria, E-Series vans, and F-Series trucks. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
